Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

This book provides a broad framework for scholar-practitioners to assist parties in conflict to collaboratively and comprehensively analyze and address diverse conflicts using all-manner of conflict interventions and theories emerging out of the twin fields of conflict resolution and peace studies. The generalist approach, which emphasizes both ‘ways of doing’ and skills, as well as ‘ways of being’ and principles, rests on solid theoretical foundations and evaluation research is integral to the approach.

O artigo procura argumentar contra a ideia de que a filosofia da história de Kant contaria com dois modelos de fundamentação: um modelo oficial, de natureza hipotético-teleológica, e outro hermenêutico-explicativo, que, porém, acabaria por implodir o sistema. Trata-se de mostrar que há um único modelo, de natureza hermenêutica-explicativa, que não obstante faz uso de princípios hipotético-teleológicos. Mais ainda, que tal modelo está presente ao longo de diversos momentos do sistema, como na Doutrina do Direito, ou na Religião nos limites da (...) simples razão. The article argues against the idea that Kant's philosophy of history would have included two types of foundation: an official model, hypothetical and teleological in nature, and other hermeneutic-explanatory, the last one that eventually would implode the system. The aim is to show that there is a single model, of hermeneutics-explanatory nature, which nevertheless makes use of hypothetical and teleological principles, and that such a model is present at various moments throughout the system, as in the Doctrine of Right, or in the Religion within the limits of pure reason.

Esta investigación analiza la presencia del discurso eurocéntrico en los manuales de Historia del Arte de Bachillerato desde una dimensión sociogenética. La muestra se compone de ejemplares pertenecientes a editoriales españolas de alcance nacional (Anaya, ECIR, Ediciones Ruiz, SM, Teide y Vicens Vives) en una cronología que comprende los distintos periodos por los que ha atravesado la materia entre 1953 y 2006. El estudio deriva de la aplicación de un guion de análisis documental que contempla, entre sus variables, la construcción (...) de identidades. Los resultados muestran la presencia y resistencia sociohistórica del discurso eurocéntrico en los manuales de Historia del Arte analizados, tendiéndose con ello a la construcción, reproducción y esencialización de identidades etnocéntricas. De este modo, para ahondar en la formación de una ciudadanía crítica, se hace necesario replantear los enfoques y las finalidades que fundamentan el relato de la Historia del Arte escolar en recursos como el que nos ocupa en este trabajo.

Esports have transformed playing video games into a competitive activity that bears similarities to sports and the processes of sportization. Taking as a starting point the concept of sports as competitive games, the objective of this work is to analyse the sportization of esports, as well as the impact of esports on the concept of sports and their implications on sports in the immediate future. Sports and esports are two different realities that interact with each other. This is a conceptual (...) problem for sports, and it also defines a practical challenge in the immediate future of sports. The virtual environment offers new possibilities in sports, such as broadening the possibilities of confrontation and competition development, contributing to reducing the environmental impact of certain sports, improving safety and maintaining the physical integrity of athletes, and increasing social justice and equality of chances in sports competitions. The challenge, therefore, is to try to bring esports and sports closer together, even moving toward hybrid sports, as addressed throughout this article. (shrink)

The overflow of scientific literature stimulates poor reading habits which can aggravate science's reproducibility crisis. Thus, solving the reproducibility crisis demands not only methodological changes, but also changes in our relationship with the scientific literature, especially our reading habits. Importantly, this does not mean reading more, it means reading better.

L’auteur présente trois témoignages. Le premier montre l’influence que la figure de frère Charles de Jésus a exercée sur lui et sur ceux qui l’ont accompagné en pèlerinage. Le second explique pourquoi, aux yeux de l’auteur, le Père de Foucauld peut être considéré comme un martyr de la foi et de la charité. Le troisième raconte comment, mettant ses pas dans les pas de frère Charles, l’auteur a passé presque deux ans dans un ermitage, sur l’Assekrem, dans le Hoggar. C’est (...) là qu’est née l’intuition fondatrice des Fraternités Monastiques de Jérusalem. (shrink)

In recent years there has been a wealth of studies investigating how memories are allocated in the hippocampus. Some of those studies showed that it is possible to manipulate the identity of neurons recruited to represent a given memory without affecting the memory's behavioral expression. Those findings raised questions about how the hippocampus represents memories, with some researchers arguing that hippocampal neurons do not represent fixed stimuli. Herein, an alternative hypothesis is argued. Neurons in high‐order brain regions can be tuned (...) to multiple dimensions, forming complex, abstract representations. It is argued that such complex receptive fields allow those neurons to show some flexibility in their responses while still representing relatively fixed sets of stimuli. Moreover, it is pointed out that changes induced by artificial manipulation of cell assemblies are not completely redundant—the observed behavioral redundancy does not imply cognitive redundancy, as different, but similar, memories may induce the same behavior.

Como alternativa a los múltiples acercamientos y estudios sobre la filosofía de Nishida Kitarõ, en este trabajo se quiere presentar un avance de investigación sobre una cuestión normalmente obviada en las interpretaciones de la obra del filósofo. Se querrá mostrar cómo una mirada atenta a la idea de símbolo y las menciones a la poesía simbolista en la obra de Nishida ofrecen una clave plausible para una mejor comprensión de su sistema de la autoconciencia en obras como Intuición y reflexiónen (...) la autoconciencia o Los problemas de la conciencia.

La tensión entre una concepción oligárquica y una concepción democrática de la política corre pareja a la tensión entre una concepción elitista y otra universalista del conocimiento. Hasta qué punto el texto platónico del Político sostiene ambos extremos de las dos tensiones es algo que también se relaciona con la complejidad de la metáfora náutica que gobierna el argumento político. The tension between an oligarchical and a democratic conception of politics is parallel to the tension between an elitist or a (...) universalist conception of knowledge. Both poles of both tensions are, in the platonic text Statesman, related to the complexity of the nautical metaphor that governs the political argument. (shrink)

The example of the bees, as they appear in Plato’s Phaedo, taken up again in Aristotle’s Politics and in Hobbes’ commentary contained in Leviathan, shows the potential of the phenomenological reading of examples as a method of understanding the basis on which philosophical thought is determined. Sign and communication are peculiar to gregarious and political animal life. In seeking to embody the Aristotelian concept of lógos in the context of a living community, as the basis for interaction and co-existence, we (...) must be sure that our interpretation does not reduce it to what, according to Aristotle, is simply animal behaviour. The Platonic sequence “ass, wolf, bee, god” situates the model of political life between a life in injustice and a life in wisdom. The Aristotelian variationdetermines the lógos on what is just and what is unjust as a natural increment in lucidity, compared with the mere exercising of gregariousness and sociability. Hobbes’ inversion of the Aristotelian example considers a natural reality in the light of the distortions that complicate and make it impossible. Hobbes thus shifts human politics towards artificiality that renders it viable. In each case, the example holds up a different mirror to the same reality. (shrink)

Eric Voegelin's Political Readings fills a critical void by providing a original approach to studying the work of Eric Voegelin, one of the major political philosophers of the twenty first century. Across six chapters a group of experts guide the reader from classical to modern times presenting six political philosophers who have had an impact on the life and philosophical production of Eric Voegelin. Philosophers examined include Plato, Aristotle, Saint Augustine, Hobbes, Weber and Kelsen. Through this innovative structure the chapters (...) collectively illustrate how Voegelin was an exceptional thinker through his engagement with political philosophers both modern and antique. The plurality of unique, academic perspectives and voices enriches our understanding of Voegelin's own thought while also encouraging a re-think of ancient and modern thinkers, and the transformation and continuity between these. Designed for students and scholars alike, Eric Voegelin's Political Readings will appeal to all those with an interest in Voegelin as well as readers familiar with classical and modern political philosophers.

Hobbes redefines his conception of liberty in the Leviathan as the absence of external impediments to motion. Power, on the other hand, refers to the body’s intrinsic dimension, that is, to the faculties possessed by each individual. There thus appears to be a clear distinction between liberty and power in Hobbes’ political philosophy. Taking into consideration Hobbes’ Latin works, however, in which he uses two different terms to refer to power: at times potestas and others potentia, such a distinction may (...) need to be revisited. As we will argue, there is a marked relation between liberty and power when considering human sociability. In this way, the aim of the article is to discuss Hobbes’ conception of power, through the pages of the Leviathan and De Homine, trying to clarify its complex, even ambiguous relation with his conception of liberty.

After Lavoisier's execution, the leading French chemists were Antoine-François Fourcroy , Louis-Bernard Guyton de Morveau and Claude-Louis Berthollet . At the beginning of the nineteenth century, Berthollet introduced a new conception of chemical change that challenged the theory of elective affinities which had dominated chemistry for nearly a hundred years. Berthollet's new affinities raised controversy among chemists and had to coexist with the firmly established theory of elective affinities. Apart from the public debate in research articles, Berthollet's affinities also had (...) to compete with the influence of Fourcroy and his school in the textbook market. This paper seeks to assess the extent to which French textbooks published at the beginning of the nineteenth century were committed to Berthollet's innovation, and how they contributed to its marginalization.

El presente trabajo busca reflexionar, desde la perspectiva de los estudios interartísticos, sobre la práctica narrativa de Adolfo Couve, escritor y pintor chileno que tematiza el mundo plástico en toda su producción narrativa. A partir de una concepción desprejuiciada respecto de lo marginal, de la fealdad y la miseria, el autor despliega una mirada alterna sobre los espacios de borde en busca de la reivindicación de la miseria, a la vez que relativizar el canon estético que prestigia temas y motivos (...) lejanos al campo de referencia de quienes habitan el borde. La exhibición de aquellos espacios, los personajes y los paisajes minoritarios, su composición plástica y narrativa, sin embargo, dialogan permanentemente con la tradición pictórica de elite.

Graphical AbstractThis paper discusses how our bad reading habits are starting to influence how we write. This short abstract and the picture next to it summarize the arguments in this paper. Just kidding, they do not. One really needs to read the paper for that.

This paper publishes for the first time 132 conjectures by Nicolaus Heinsius on Ovid’s Metamorphoses 1‒4. The value and possible motivations of each proposal are briefly assessed.

Classical propositional logic plays a prominent role in industrial applications, and yet the complexity of this logic is presumed to be non-feasible. Tractable systems such as depth-bounded boolean logics approximate classical logic and can be seen as a model for resource-bounded agents whose reasoning style is nonetheless classical. In this paper we first study a hierarchy of tractable logics that is not defined by depth. Then we extend it into a modal logic where modalities make explicit the assumptions discharged in (...) propositional proofs, thereby expressing blueprints for proofs. A natural deduction system is provided that permits to reason about and manage such proof blueprints. (shrink)
